4.2.7.2 Special device configuration
Modbus register 1300
Modbus register 1300 can be used to configure the following settings:
•
Bit 0:
•
0 = voltage indication, phase – neutral conductor
•
1 = voltage indication, phase – phase
•
Bit 1:
•
0 = PO 1 active energy, PO 2 reactive energy
•
1 = PO 1 active energy, PO 1 active energy
Modbus register 1301
Modbus register 1301 can be used to change the direction of current and the
phase sequence as follows:
•
Bit 0:
•
0 = Positive power flow from top to bottom (outgoer)
•
1 = Positive power flow from bottom to top (feeder unit – default
value)
•
Bit 1:
•
0 = Phase order OK, as indicated on the device.
•
1 = phases 1 and 3 are swapped.
Modbus registers 1400 - 1405
The firmware version is saved in registers 1400 to 1405.
4.2.7.3 Digital outputs (Modbus function code 5)
The range from 0 to 9 is available for the digital outputs.
The outputs are optically decoupled semiconductor outputs.
•
0, 1: Digital outputs of NZM…-XMC-… basic device
•
2 to 5: for expansion card 1
•
6 to 9: for expansion card 2
4.2.7.4 Digital inputs
The range from 10 to 19 is available for the digital inputs.
•
10, 11: Digital outputs of NZM…-XMC-… basic device
•
12 to 15: for expansion card 1
•
16 to 19: for expansion card 2
4.2.7.5 Reset (coil 2000)
Resets the device. The setting is returned to 0.
